[Seaside] html images

[Dan Shafer]

Turns out this may have been a false alarm. My colleague was using an  
old Squeakland.org image. When he moved to the newest Squeak.org  
image, the PNG stuff, at least, cleared up right away. He's now very  
happy.

Not sure about ImageReadWriter in all of that but PNGReadWriter seems  
fine, according to him.

I'm still muddling about in the middle of the Seaside doing basic  
stuff, so I'm not in a position to test any of that.
